Mechanism for Memory Reduction in Picture-In-Picture Video Generation

1. A method comprising: receiving, from a transmitting device, a plurality of video streams at a receiving device coupled to the transmitting device, wherein a first video stream of the plurality of video streams is designated to be displayed as a main video and one or more other video streams of the plurality of video streams are designated to be displayed as one or more sub videos to the main video; transforming the one or more other video streams into the one or more sub videos; temporarily holding the one or more sub videos in a compressed frame buffer, and wherein the one or more sub videos are predictively compressed according to a down-sampling ratio prior to being held in the compressed frame buffer; and merging, via on-the-fly pixel replacement, the main video and the one or more sub videos into a final video image capable of being displayed on a single screen utilizing a display device, wherein the on-the-fly pixel replacement includes replacing a first set of pixels of the screen occupied by a section of the main video with a second set of pixels relating to the one or more sub videos, and wherein the one or more sub videos are predictively decompressed in advance of the second set of pixels relating to the one or more sub videos replacing the first set of pixels relating to the main video, wherein the predictive compression and decompression are performed in real-time and include frame-based or row-based.

2. The method of claim 1 , wherein transforming further comprises: down-sampling the one or more other video streams according to a defined down-sampling ratio; transporting the one or more down-sampled videos to a compressor via a first line buffer; and compressing the one or more down-sampled videos.

3. The method of claim 1 , wherein transforming further comprises trans-porting the one or more compressed down-sampled videos as the one or more sub videos into the compressed frame buffer.

4. The method of claim 1 , wherein transforming further comprises: decompressing the one or more compressed down-sampled videos; and transporting the one or more decompressed down-sampled videos as the one or more sub videos to a pixel transformation unit via a second line buffer.

5. The method of claim 1 , further comprising transporting the first video as the main video directly to the pixel replacement unit.

6. The method of claim 1 , wherein pixel replacement further comprises one or more of extracting pixels per color depth, performing color conversion, and down-sampling per resolution of the one or more other video streams.

7. The method of claim 1 , wherein occupying the section comprises pixel replacing main video pixels of the section with sub video pixels, wherein pixel re-placing further includes color adjusting the sub video pixels following a color depth formatting of the main video pixels of the main video.

8. The method of claim 1 , further comprising displaying the final video image on a display screen of the display device.

9. A system comprising: a data processing device having a storage medium and a processor coupled with the storage medium, the data processing device further having a mechanism, wherein the mechanism to: receive, from a transmitting device, a plurality of video streams at a receiving device coupled to the transmitting device, wherein a first video stream of the plurality of video streams is designated to be displayed as a main video and one or more other video streams of the plurality of video streams are designated to be displayed as one or more sub videos to the main video, transform the one or more other video streams into the one or more sub videos, temporarily hold the one or more sub videos in a compressed frame buffer, and wherein the one or more sub videos are predictively compressed according to a down-sampling ratio prior to being held in the compressed frame buffer, and merge, via on-the-fly pixel replacement, the main video and the one or more sub videos into a final video image capable of being displayed on a single screen utilizing a display device, wherein the on-the-fly pixel replacement includes replacing a first set of pixels of the screen occupied by a section of the main video with a second set of pixels relating to the one or more sub videos, and wherein the one or more sub videos are predictively decompressed in advance of the second set of pixels relating to the one or more sub videos replacing the first set of pixels relating to the main video, wherein the predictive compression and decompression are performed in real-time and include frame-based or row-based.

10. The system of claim 9 , wherein when transforming, the mechanism is further to: down-sample the one or more other video streams according to a defined down-sampling ratio; transport the one or more down-sampled videos to a compressor via a first line buffer; and compress the one or more down-sampled videos.

11. The system of claim 9 , wherein when transforming, the mechanism is further to transport the one or more compressed down-sampled videos as the one or more sub videos into the compressed frame buffer.

12. The system of claim 9 , wherein when transforming, the mechanism is further to: decompress the one or more compressed down-sampled videos; and transport the one or more decompressed down-sampled videos as the one or more sub videos to a pixel transformation unit via a second line buffer.

13. The system of claim 9 , wherein the mechanism is further to transporting the first video as the main video directly to the pixel replacement unit.

14. An apparatus comprising a data processing device having a storage medium and a processor coupled with the storage medium, the processor to: receive, from a transmitting device, a plurality of video streams at a receiving device coupled to the transmitting device, wherein a first video stream of the plurality of video streams is designated to be displayed as a main video and one or more other video streams of the plurality of video streams are designated to be displayed as one or more sub videos to the main video; transform the one or more other video streams into the one or more sub videos; temporarily hold the one or more sub videos in a compressed frame buffer, and wherein the one or more sub videos are predictively compressed according to a down-sampling ratio prior to being held in the compressed frame buffer; and merge, via on-the-fly pixel replacement, the main video and the one or more sub videos into a final video image capable of being displayed on a single screen utilizing a display device, wherein the on-the-fly pixel replacement includes replacing a first set of pixels of the screen occupied by a section of the main video with a second set of pixels relating to the one or more sub videos, and wherein the one or more sub videos are predictively decompressed in advance of the second set of pixels relating to the one or more sub videos replacing the first set of pixels relating to the main video, wherein the predictive compression and decompression are performed in real-time and include frame-based or row-based.

15. The apparatus of claim 14 , wherein when transforming, the processor is further to: down-sample the one or more other video streams according to a defined down-sampling ratio; transport the one or more down-sampled videos to a compressor via a first line buffer; and compress the one or more down-sampled videos.

16. The apparatus of claim 14 , wherein when transforming, the processor is further to transport the one or more compressed down-sampled videos as the one or more sub videos into the compressed frame buffer.
